nothing
It means that your mind is using the image of your friend to represent yourself, and "doing drugs" symbolizes something you are doing that you know is wrong. You may be in denial, fooling yourself into believing that you are not "really" involved with this behavior, or that you can quit any time you want. However, the dream is saying that whatever this represents is just like doing drugs - you don't realize how addicted you are becoming. The dream uses your best friend's image because you care about this friend and don't want them involved in self-destructive behavior. The dream is telling you to care about yourself in the same way you care about your best friend.
In my opinion no someone going to cheat regardless if they are doing drugs or not, it may influence them more but some people know there limit on cheating and some don't
dreaming about needles and threads depends on what the needles and threads are doing in you dream. Sometimes it means that you need to mend somthing with someone right a wrong or that someone is trying to mend it with you but you don't want to or dont' know that they are wanting to.
Wake up
I do not know but you should not be doing drugs even though its a plant but w/e try google or ask someone you trust.....
The dream suggests a lack of information. You do not know as much as you think you know about someone in your life.
Many parents know, but aren't doing anything about it. The amount of parents that know and are doing something about it is probably around 25%.
honestly you will never know for sure unless there is a drug test. If you find that he is doing drugs you need to ask yourself if you can be with him. If you continue the relationship you cant keep pestering him by asking if he does drugs.
You or someone else that you know are thinking that they are pregnant and they want to know if its true.
Why do you wanna know? You shouldn't be doing drugs!
It's just a dream, if you want to know whether you're attracted to someone in your class then ask yourself.
The dream is not about this "someone you know." Instead, this someone represents yourself. Your own mind is showing you that you have lost track of a part of yourself.
